Chinese officials are finally admitting that the “throat-choking, eye-watering, blinding smog,” as Newser puts it, isn’t just a little afternoon fog. As officials from China, the world’s biggest carbon emitter in the world, are at the Durban summit to negotiate a binding agreement to reduce emissions, the government is also acknowledging they are facing a problem with pollution.

The smog has been so bad in the last few days that a number of flights have been canceled out of Beijing International Airport, the world's second busiest hub. Out on the streets, many residents have started wearing masks. State-run media that previously complained about the recurring persistent “fog” are now acknowledging the health threats the country’s pollution presents. China’s state-run Global Times published an editorial Wednesday saying the nation needed to “face the reality... our pollution has become severe.”

While officially, Beijing's air quality is improving, the U.S. Embassy’s pollution monitor in Beijing Tuesday read “very unhealthy.” On Sunday, Bloomberg reported the pollution was so bad it was beyond the monitor's ability to measure it. Below, see video and images of the incredible smog:
